Planet-like rotary type overhauling robot suitable for multi-size inhaul cables

Abstract

The invention discloses a planet-like rotary type overhauling robot suitable for multi-size inhaul cables, and relates to the field of crawling robots for overhauling the surfaces of the inhaul cables of an inhaul cable bridge. The planet-like rotary type overhauling robot suitable for the multi-size inhaul cables is provided according to the difference of the sizes of the inhaul cables in cooperation with the shape characteristics of the surfaces of the inhaul cables. The planet-like rotary type overhauling robot comprises an inhaul cable polishing device, an inhaul cable cleaning device, an inhaul cable spraying device, an arc guide rotating platform, a robot base body, a pressing climbing device and an inhaul cable surface quality inspection mechanism. The planet-like rotary type overhauling robot has the technical characteristics that a repairing device is modularized; the repairing device does planetary-like rotary motion around the inhaul cables while working; the pressing climbing device can adjust the pressing force of climbing wheels; and a shear fork structure in the repairing device is matched with a guide rail sliding block to adjust the distance between a tail end executing structure and the surfaces of the inhaul cables, so that high-altitude operation of workers is avoided, the repairing device adapts to the inhaul cables of different sizes, and the repairing efficiency, precision and accuracy are improved.

Description

technical field [0001] The invention belongs to the field of crawling robots, in particular to a planetary rotary maintenance robot applicable to multi-size cables. Background technique [0002] As the preferred bridge type of long-span bridges, cable-stayed bridges have been widely built in coastal cities in recent years. Cable-stayed bridges not only have the advantage of a large span range, but also have a more beautiful appearance than ordinary bridges. The stability is also superior. The construction of cable-stayed bridges is more convenient than ordinary bridges, and the materials required to manufacture a cable-stayed bridge are also more economical than other types of bridges. With the advancement of construction technology of cable-stayed bridges and the continuous emergence of new materials, more and more cable-stayed bridges will be built in coastal cities in my country in the future, and will become the main way of urban bridges in our country.

Problems solved by technology

[0003] Although the construction cost of cable-stayed bridges is less than that of other types of bridges, the maintenance work of cable-stayed bridges is more difficult than other types of bridges

The maintenance of the cables of the cable-stayed bridge is not only to ensure the stability and safety of a bridge, but also for the cable-stayed bridge itself, if the corresponding maintenance work is not carried out for a long time, the entire cable will be damaged In severe cases, more cables will be damaged. The only solution for cable damage is to change cables. For cable-stayed bridges, changing cables is extremely inconvenient, because changing cables will lead to the closure of the entire bridge, affecting The normal operation of the traffic, and the fraud of the cable is very high, and the frequent change of the cable will cause a lot of unnecessary economic measures

The cable replacement work of the cable bridge is a special and complicated environment, accompanied by the influence of high-altitude wind load and vibration, which threatens the safety of the cable maintenance personnel, and most of the current cable crawling robots only have detection functions. Some crawling robots are equipped with a maintenance device for the cable surface, but the comprehensive maintenance of the cable surface is not realized. It is still necessary for the staff to detect and manually maintain the cable surface. Purpose
